Sin167cos107-cos167sin107
insens350 [35]
Sin 167 = 0.22495

cos 107 = -0.29237

cos 167 = -0.97437

sin 107 = 0.95630

(sin 167)(cos 107) - (cos 167)(sin 107)

(0.22495)(-0.29237) - ( -0.97437)(0.95630)

= 0.86602

hope this helps :)

You can plug 1350 or less watts without overloading the circuit.

Step-by-step explanation:

Given,

Circuit overloads at = 2400 watts

Electricity consumed by portable heater = 1050 watts

Let,

x be the additional number of watts you can plug in.

Portable heater + additional watts ≤ Overloading limit

1050 + x ≤ 2400

Subtracting 1050 from both sides

1050-1050+x\leq 2400-1050\\x\leq 1350

You can plug 1350 or less watts without overloading the circuit.
